Overview
The MC14094B, produced by onsemi, is an integrated circuit that combines an 8-stage shift register with a data latch for each stage and features three-state outputs. This component is designed to handle serial data shifting and storage efficiently, making it suitable for various digital circuit applications. Data is shifted on the positive clock transition, and the QS output is optimized for high-speed cascaded systems, while the Q'S output is shifted on the following negative clock transition for low-speed systems. The device also includes input diode protection and is pin-for-pin compatible with the CD4094B.
